SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

Every single head on the market has issues when they age. PGP's leak from the collar but seldom stick up, Nelson's are a pain to adjust and stick up, Toro 800's stick up but rarely stop rotating, Toro 700's rarely stick up but stop rotating, Rainbird 5000's stop rotating.... The only head I've seen worth a darn is the Hunter 1-20, but good luck trying to stay competitive installing a system with these.

You have to wonder just when did a pro ever take a piece of one brand of sprinkler head, and put it into another make of head, in order to effect a repair.
